Why aren't scientists trying to find a method to use animal brains as processing machines?
Analog devices are plagued by noise. Digital signals are internally coded to correct a low incidence of single byte errors and detect uncorrectable multiple byte errors.

A very large volume of animal processing occurs locally, independent of the brain. Insect walking is mostly not a concious act Your retina does substantial signal processing locally. Your reflexes are not brain-connected but instead loop the spinal cord.
